PS Business Parks, Inc. Reports Results for the Quarter Ended March 31, 2021

GLENDALE, California—PS Business Parks, Inc. (NYSE:PSB) reported operating results for the three months ended March 31, 2021.

Operating Results for the Three Months Ended March 31, 2021

Net income allocable to common shareholders for the three months ended March 31, 2021 was $27.9 million, or $1.01 per diluted common share. Net operating income (“NOI”) attributable to the Company’s Same Park portfolio (defined below) was $70.3 million for the three months ended March 31, 2021, representing a decrease of 0.6% over the same period in 2020.

The Company also reports NOI, a measure that is not defined in accordance with U.S. generally accepted accounting principles (“GAAP”), on a cash basis, which excludes non-cash rental income such as amortization of deferred rent receivable and other non-cash items, and also excludes rents that have been deferred or abated during the period. Same Park Cash NOI was $69.9 million for the three months ended March 31, 2021, representing a decrease of 0.2% over the same period in 2020. The change in Same Park Cash NOI for the three months ended March 31, 2021 was driven by 1.2% cash rental income growth offset by 4.6% growth in adjusted cost of operations. Weighted average occupancy for the Company’s Same Park portfolio during the three months ended March 31, 2021 was 92.4% compared to 92.8% in the same period in 2020. Total portfolio weighted average occupancy was 92.4% during the three months ended March 31, 2021, compared to 92.9% for the same period in 2020.

The following table details the change in Same Park rental income for the three months ended March 31, 2021 and 2020 (in thousands):

	For the Three Months
	Ended March 31,
	2021			2020			Change

Non-Cash Rental Income (1)		437			753			(316	)
Total rental income	$	99,995		$	99,130		$	865

⁽¹⁾ Non-cash rental income includes amortization of deferred rent receivable (net of write-offs), in-place lease intangible, tenant improvement reimbursement, and lease incentive intangible.

Additional detail on Same Park NOI and Same Park Cash NOI for the three months ended March 31, 2021 is provided in the Property Operations–Same Park Portfolio section below.

Funds from Operations (“FFO”), Core FFO, and Funds Available for Distribution (“FAD”)

FFO for the three months ended March 31, 2021 was $1.67 per share, representing a decrease of 2.5% from the same period in 2020. The decrease in FFO per share was the result of flat NOI and $1.1 million higher general and administrative expense driven by $0.7 million higher stock-compensation expense. FFO is a non-GAAP measure defined by the National Association of Real Estate Investment Trusts and generally represents GAAP net income before (i) real estate depreciation and amortization expense, (ii) gains or losses on sales of operating properties, and (iii) land and impairment charges on real estate assets.

Core FFO per share was equal to FFO per share for both the three months ended March 31, 2021 and 2020. The Company defines Core FFO as FFO excluding the impact of (i) charges related to the redemption of preferred stock and (ii) other nonrecurring income or expense items as appropriate, neither of which were incurred by the Company during the three month periods ended March 31, 2021 and 2020.

FAD for the three months ended March 31, 2021 was $50.3 million, representing an increase of 2.0% from the same period in 2020. The increase in FAD for the three months ended March 31, 2021 was largely attributable to lower recurring capital expenditures incurred as compared to the same period in 2020. FAD is a non-GAAP measure that represents Core FFO adjusted to (i) deduct recurring capital improvements and capitalized tenant improvements and lease commissions and (ii) remove certain non-cash income or expenses, such as amortization of deferred rent receivable and stock compensation expense.

FFO, Core FFO, and FAD are not substitutes for GAAP net income. Other real estate investment trusts (“REITs”) may compute FFO, Core FFO, and FAD differently, which could inhibit comparability. The Company believes its presentations of FFO, Core FFO, and FAD assist investors and analysts in analyzing and comparing the operating and financial performance between reporting periods. Additional information about these measures is included on the Company’s quarterly report on Form 10-Q.

Leasing Production¹

During the three months ended March 31, 2021, the Company executed leases on 2.0 million square feet in 569 transactions compared to 1.9 million square feet in 495 transactions for the three months ended March 31, 2020. Weighted average cash rental rate growth on leases executed during the three months ended March 31, 2021, was 5.7%, while average net effective rent² growth was 14.8%. The average lease term of all leases executed during the three months ended March 31, 2021 was 3.2 years with associated average transaction costs (tenant improvements and leasing commissions) of $2.59 per square foot. For comparative purposes, average lease term and transaction costs on leases executed in the same period of 2020 were 3.8 years and $3.08 per square foot, respectively.

Property Operations–Same Park Portfolio

The Company believes that evaluation of the Same Park portfolio, defined as all properties owned and operated as of March 31, 2021 that were acquired prior to January 1, 2019, provides an informative view of how the Company’s portfolio has performed over comparable periods. As of March 31, 2021, the Same Park portfolio consisted of 26.3 million rentable square feet, or 94.6% of the 27.8 million rentable square feet in the Company’s total portfolio, and excludes the Company’s 95.0% interest in a 395-unit multifamily property. For the three months ended March 31, 2021 and all comparative periods presented herein, the Company has excluded 442,000 square feet of assets held for sale. The assets held for sale represent a 244,000 square foot office business park located in Herndon, Virginia, and a 198,000 square foot office oriented flex business park located in Chantilly, Virginia. The Company noted that the potential sale of these assets is consistent with its strategy to opportunistically divest of non-strategic assets.

¹  Leasing production excludes production metrics from assets held for sale as of March 31, 2021.

²  Net effective rent represents average rental payments for the term of a lease on a straight-line basis, excluding operating expense reimbursements.

Cash Rental Income per available foot (11)	$	15.16		$	14.98			1.2	%

⁽¹⁾ Cash Rental Income represents rental income excluding Non-Cash Rental Income (defined below). Included in the calculation of Same Park Cash Rental Income are (a) lease buyout income of $0.4 million and $0.3 million for the three months ended March 31, 2021 and 2020, respectively, and (b) accounts receivable write-offs of $0.0 and $0.1 million for the three months ended March 31, 2021 and 2020, respectively. Cash rental income does not include deferred and abated rental income of $0.3 million and $0.0 for the three months ended March 31, 2021 and 2020, respectively.

⁽²⁾ Non-Cash Rental Income represents amortization of deferred rent receivable, amortization of above and below market rents, net, and amortization of lease incentives and tenant improvement reimbursements. Same Park Non-Cash Rental Income is presented net of deferred rent receivable write-offs of $0.1 million for both of the three months ended March 31, 2021 and 2020.

⁽³⁾ Adjusted Cost of Operations, as presented above, excludes stock compensation expense for employees whose compensation expense is recorded in cost of operations, which can vary significantly period to period based upon the performance of the Company.

⁽⁴⁾ The Company utilizes NOI, a non-GAAP financial measure, to evaluate the operating performance of its business parks. The Company defines NOI as rental income less Adjusted Cost of Operations. The Company believes NOI assists investors in analyzing the performance of its real estate by excluding (i) corporate overhead (i.e., general and administrative expense) because it does not relate to the direct operating performance of the real estate, (ii) depreciation and amortization expense because it does not accurately reflect changes in the fair value of the real estate, and (iii) stock compensation expense because this expense item can vary significantly from period to period and thus impact comparability across periods.

⁽⁵⁾ The Company utilizes Cash NOI, a non-GAAP financial measure, to evaluate the cash flow performance of our business parks, and we believe investors utilize this metric for the same purpose. The Company defines Cash NOI as Cash Rental Income less Adjusted Cost of Operations.

⁽⁶⁾ NOI margin is computed by dividing NOI by rental income.

⁽⁷⁾ Cash NOI margin is computed by dividing Cash NOI by Cash Rental Income.

⁽⁸⁾ Revenue per occupied square foot is computed by dividing rental income for the period by weighted average occupied square feet for the same period. Revenue per occupied square foot for the three month period shown is annualized.

⁽⁹⁾ Revenue per Available Square Foot (RevPAF) is computed by dividing rental income for the period by weighted average available square feet for the same period. RevPAF for the three month period shown is annualized.

⁽¹⁰⁾ Cash Rental Income per occupied square foot is computed by dividing Cash Rental Income for the period by weighted average occupied square feet for the same period. Cash rental income per occupied square foot for the three month period shown is annualized.

⁽¹¹⁾ Cash Rental Income per Available Square Foot is computed by dividing Cash Rental Income for the period by weighted average available square feet for the same period. Cash rental income per available square foot for the three month period shown is annualized.

COVID-19 Pandemic/Rent Collections Update

The COVID-19 pandemic has had and is expected to continue to have an impact on our operations and capital plans. During the three months ended March 31, 2021, the Company granted $0.2 million of deferred rent and $0.1 million of rent abatement. Since the onset of the COVID-19 pandemic, the Company has granted rent relief to 398 customers (approximately 11.0% of total customers based on rental income) including $5.9 million of rent deferral and $1.4 million of rent abatement. As of March 31, 2021, the Company collected $3.9 million, or 98.5%, of the scheduled repayments of COVID-19 related rent deferrals billed through March 1, 2021. An additional $1.1 million of rent deferral repayments are scheduled to be repaid by customers between April 1, 2021 and December 31, 2021, with an additional $0.8 million thereafter.

As of April 26, 2021, the Company had collected 98.8%³ of billed revenue during the three months ended March 31, 2021. Further, the first quarter of 2021 marked the third consecutive quarter of normal accounts receivable write-off volume. During the three months ended March 31, 2021, the Company wrote off $0.0 of accounts receivable, which is lower than the $0.1 million written off during the three months ended March 31, 2020. Also during the three months ended March 31, 2021, the Company wrote off deferred rent receivables of $0.1 million, which is comparable to the $0.1 million written off during the three months ended March 31, 2020.

As of April 26, 2021, the Company had open rent relief requests from approximately 1% of its customers. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations–Overview, Impact of COVID-19 Pandemic” in our Form 10-Q for the quarter ended March 31, 2021 for more information.

Provided within this supplemental information package are measures not defined in accordance with U.S. generally accepted accounting principles (“GAAP”). We believe our presentation of these non-GAAP measures assists investors and analysts in analyzing and comparing our operating and financial performance between reporting periods. These non-GAAP measures discussed below are not substitutes of other measures of financial performance presented in accordance with GAAP. In addition, other real estate investment trusts (“REITs”) may compute these measures differently, so comparisons among REITs may not be helpful.

Adjusted Cost of Operations – Adjusted cost of operations represents cost of operations, excluding non-cash stock compensation expense for employees whose compensation expense is recorded in cost of operations, which can vary significantly period to period based upon the performance of the Company. The GAAP measure most directly comparable to adjusted cost of operations is cost of operations.

Assets sold or held for sale – Assets sold or held for sale represents 113,000 square feet of assets sold in January 2020 and 40,000 square feet of assets sold in September 2020 and includes 442,000 square feet of assets held for sale. The assets held for sale represent a 244,000 square foot office business park located in Herndon, Virginia, and a 198,000 square foot office oriented flex business park located in Chantilly, Virginia.

Average Net Effective Rent Growth – Average net effective rent growth represents the weighted average percentage change in net effective rents for leases executed during a period compared against the prior leases for the same units. Net effective rent represents average rental payments for the term of a lease on a straight-line basis, excluding operating expense reimbursements

Cash NOI – We utilize cash NOI to evaluate the cash flow performance of our business parks. Cash NOI represents NOI adjusted to exclude non-cash items included in rental income and in cost of operations. The non-cash rental income includes amortization of deferred rent receivable (net of write-offs), in-place lease intangible, tenant improvement reimbursement, and lease incentive intangible. The non-cash expense is equal to stock compensation expense for employees whose compensation expense is recorded in cost of operations. We believe that cash NOI assists investors in analyzing cash flow performance of our business parks. The GAAP measure most directly comparable to cash NOI is net income.

Cash Rental Income – Cash rental income represents rental income, excluding non-cash rental income, specifically amortization of deferred rent receivable (net of write-offs), in-place lease intangible, tenant improvement reimbursement, and lease incentive intangible.

Cash Rental Income per Available Square Foot – Cash rental income per available square foot is computed by dividing Cash Rental Income for the period by weighted average available square feet for the same period. Cash rental income per available square foot for the three month period is annualized.

Cash Rental Income per Occupied Square Foot – Cash rental income per occupied square foot is computed by dividing Cash Rental Income for the period by weighted average occupied square feet for the same period. Cash rental income per occupied square foot for the three month period is annualized.

Cash Rental Rate Change – Cash rental rate change percentages are computed by taking the percentage difference between outgoing rents (including estimated expense recoveries) and incoming rents (including estimated expense recoveries) for leases executed during the period. Leases executed on spaces vacant for more than the preceding twelve months have been excluded.

Core FFO and Core FFO per share – Core FFO represents FFO excluding the net impact of (i) income allocated to preferred shareholders to the extent redemption value exceeds the related carrying value and (ii) other nonrecurring income or expense items as appropriate. Core FFO per share represents Core FFO allocable to diluted shares and units divided by the weighted average diluted shares and units. We believe our presentation of Core FFO and Core FFO per share assists investors and analysts in analyzing and comparing our operating and financial performance between reporting periods. The GAAP measures most directly comparable to Core FFO and Core FFO per share are net income and earnings per share, respectively.

Earnings before Interest, Taxes, Depreciation and Amortization for Real Estate (“EBITDAre”) – EBITDAre is defined by the National Association of Real Estate Investment Trusts (“NAREIT”) and is often utilized to evaluate the performance of real estate companies. EBITDAre is calculated as GAAP net income before interest, depreciation and amortization and adjusted to exclude gains or losses from sales of depreciable real estate assets and impairment charges on real estate assets. We believe our presentation of EBITDAre assists investors and analysts in evaluating the operating performance of our business activities, including the impact of general and administrative expenses, and without the impact from gains or losses from sales of depreciable real estate assets. The GAAP measure most directly comparable EBITDAre is net income.

Free Cash Available after Fixed Charges – Free cash available after fixed charges represents FAD less dividends and distributions.

22

Funds Available for Distribution (“FAD”) – FAD is a non-GAAP measure that represents Core FFO adjusted to (a) deduct recurring capital improvements that maintains the condition of our real estate, tenant improvements and lease commissions and (b) remove certain non-cash rental income or expenses such as amortization of deferred rent receivable and non-cash stock compensation expense. We believe our presentation of FAD assists investors and analysts in analyzing and comparing our operating and financial performance between reporting periods. FAD is not a substitute for GAAP net cash flow in evaluating our liquidity or ability to pay dividends, because they exclude investing and financing activities presented on our statements of cash flows. The GAAP measure most directly comparable to FAD is operating cash flow from our statements of cash flows.

Funds from Operations (“FFO”) and FFO per share – FFO and FFO per share are non-GAAP measures defined by NAREIT and are considered helpful measures of REIT performance by REITs and many REIT analysts. FFO represents GAAP net income before real estate depreciation and amortization expense, gains or losses on sales of operating properties and land and impairment charges on real estate assets, which are excluded because it does not accurately reflect changes in the value of our business parks. FFO per share represents FFO allocable to diluted shares and units, divided by aggregate diluted shares and units. The GAAP measure most directly comparable to FFO and FFO per share are net income and earnings per share, respectively.

Net Operating Income (“NOI”) – We utilize NOI, a non-GAAP financial measure, to evaluate the operating performance of our business parks. We define NOI as rental income less adjusted cost of operations (described below). We believe NOI assists investors in analyzing the performance and value of our business parks by excluding (i) corporate overhead (i.e. general and administrative expenses) because it does not relate to the results of our business parks, (ii) depreciation and amortization expense because it does not accurately reflect changes in the fair value of our business parks and (iii) stock compensation expense because this expense item can vary significantly from period to period and thus impact comparability across periods. The GAAP measure most directly comparable to NOI is net income.

Non-Recurring Property Renovations – Non-recurring property renovations represents renovations that substantially enhance the value of a property, including capitalized costs associated with repositioning acquired assets.

Non-Same Park – Non-Same Park includes assets acquired on or subsequent to January 1, 2019.

Recurring Capital Expenditures – Recurring capital expenditures are capitalized costs necessary to continue to operate the property at its current economic value. Capital improvements in excess of $2,000 with a useful life greater than 24 months are capitalized. Lease transaction costs (i.e. tenant improvements and leasing commissions) of $1,000 or more for leases with terms greater than 12 months are capitalized. All leasing costs, including first generation tenant improvements and leasing commissions, are included in recurring capital expenditures.

Retained Cash – Retained cash represents free cash available after fixed charges less non-recurring property renovations and funds used for development and redevelopment.

Same Park – Same Park includes assets acquired prior to January 1, 2019.

Transaction Costs as a Percentage of Rents – Transaction costs as a percentage of rents are computed by taking the total transaction costs divided by the total rents (including estimated expense recoveries) over the term of the lease.
